I just played this game this past week. Take a plastic water bottle, regular size. Make sure its clean and dry. Now fill with wild bird seed (can use maybe rice or dry sand). Now drop things in that will fit thru the top, keeping a list as you do. Nickel, dime, penny, paper clip, pop top on soda can. Now being that is a chemo type situation guess you could try lets see perhaps hair roller, hair clip, go into dollar store and get ideas. When you have about a doz items in there. Glue cap on so no one goes in there and pours it out or such. Give each person one of these and tell them they have about 15 minutes to write down as many things as they can find in there.
You keep master list. Everyone will be shaking bottle, rolling it back and forth and having a good time. You can make these such as baby shower and use little baby items from Michaels store, even children's party and use items to match that theme. Your mind will go wild, young and old love this game trying to find items.
